Translatability of WGS typing results can simplify data exchange for surveillance and control of Listeria monocytogenes

The place classical epidemiology has confirmed to be insufficient for surveillance and management of foodborne pathogens, molecular epidemiology, utilizing genomic typing strategies, can add worth. Nevertheless, the evaluation of entire genome sequencing (WGS) information varies extensively and isn’t but absolutely harmonised. We used genomic information on 494 Listeria monocytogenes isolates from ready-to-eat meals merchandise and meals processing environments deposited within the pressure assortment of the German Nationwide Reference Laboratory to check varied procedures for WGS information evaluation and to judge compatibility of outcomes.

 

Two totally different core genome multilocus sequence typing (cgMLST) schemes, totally different reference genomes in single nucleotide polymorphism (SNP) evaluation and business in addition to open-source software program have been in contrast. Correlation of allele distances from the totally different cgMLST approaches was excessive, starting from 0.97 to 1, and unified thresholds yielded greater clustering concordance than scheme-specific thresholds. The variety of detected SNP variations might be elevated as much as an element of three.9 utilizing a selected reference genome in contrast with a normal one. Moreover, particular reference genomes improved comparability of SNP evaluation outcomes obtained utilizing totally different software program instruments. The usage of a closed or a draft particular reference genome didn’t make a distinction.

 

The harmonisation of WGS information evaluation will lastly assure seamless information alternate, however, within the meantime, data on threshold values that result in comparable clustering of isolates by totally different strategies might enhance communication between laboratories. We subsequently established a translation code between generally utilized cgMLST and SNP strategies primarily based on optimised clustering concordances. This code can work as a primary filter to establish WGS-based typing matches ensuing from totally different strategies, which opens up a brand new perspective for information alternate and thereby accelerates time-critical analyses, equivalent to in outbreak investigations.

 

Antibacterial and Antifungal Properties of Composite Polyethylene Supplies Bolstered with Neem and Turmeric

With the elevated scientific curiosity in inexperienced applied sciences, many researches have been centered on the production of polymeric composites containing naturally occurring reinforcing particles. Aside from rising mechanical properties, these additions can have a variety of attention-grabbing results, equivalent to rising the resistance to bacterial and fungal colonization.
On this work, totally different quantities of two totally different pure merchandise, specifically neem and turmeric, have been added to polyethylene to behave as a pure antibacterial and antifungal product for meals packaging purposes. Microscopic and spectroscopic characterization confirmed that fractions of as much as 5% of those merchandise might be dispersed into low-molecular weight polyethylene, whereas greater quantities couldn’t be correctly dispersed and resulted in an inhomogeneous, fragile composite.
In vitro testing carried out withEscherichia coliStaphylococcus aureus, and Candida albicans confirmed a diminished proliferation of pathogens when in comparison with the polyethylene references. Particularly, turmeric resulted in being more practical in opposition to E. coli when in comparison with neem, whereas they’d comparable performances in opposition to S. aureus. In opposition to C. albicans, solely neem was in a position to present antifungal conduct, at excessive concentrations. Tensile testing confirmed that the addition of reinforcing particles diminished the mechanical properties of polyethylene, and within the case of turmeric, it was additional diminished by UV irradiation.

An Autism-Related Mutation Impairs Neuroligin-Four Glycosylation and Enhances Excitatory Synaptic Transmission in Human Neurons

Neuroligins (NLGNs) are a category of postsynaptic cell-adhesion molecules that work together with presynaptic Neurexins (NRXNs) and regulate synapse operate. Neuroligin-4 (NLGN4) is a member of the NLGN household and consists of a singular amino-acid sequence in people that isn’t evolutionarily well-conserved in rodents. The human-specific NLGN4 gene has been reported to be mutated in lots of sufferers with autism and different neurodevelopmental problems. Nevertheless, it remained unclear how these mutations may alter the molecular properties of NLGN4 and have an effect on synaptic transmission in human neurons. Right here, we describe a severely autistic male affected person carrying a single amino-acid substitution (R101Q) within the NLGN4 gene.
When expressed in HEK293 cells, the R101Q mutation in NLGN4 didn’t have an effect on its binding affinity for NRXNs or its capability to kind homodimers. This mutation, nevertheless, impaired the maturation of NLGN4 protein by inhibiting N-linked glycosylation at an adjoining residue (N102), which is conserved in all NLGNs. In consequence, the R101Q substitution considerably decreased the floor trafficking of NLGN4 and elevated its retention within the endoplasmic reticulum and Golgi equipment. In human neurons derived from male stem-cell traces, the R101Q mutation additionally equally diminished the synaptic localization of NLGN4, leading to a loss-of-function phenotype. This mutation-induced trafficking defect considerably diminished NLGN4’s potential to kind excitatory synapses and modulate their useful properties. Considered collectively, our findings recommend that the R101Q mutation is pathogenic for NLGN4 and might result in synaptic dysfunction in autism.

SIGNIFICANCE STATEMENTA number of single amino-acid substitutions in X-linked NLGN4 (NLGN4X) gene have been recognized in autistic sufferers. Nevertheless, it remained unclear how these point-mutations may have an effect on NLGN4 properties and affect synapse operate in people. Right here, we analyzed the mechanisms of an autism-associated R101Q variant in NLGN4. We exhibit that this mutation can straight impair NLGN4’s post-translational modification (PTM) by inhibiting N-linked glycosylation. These immaturely glycosylated merchandise exhibit categorical deficits in floor trafficking and synaptic localization, and thus symbolize a loss-of-function phenotype.
